gear fixed to the inner surface of the outerring l3. r

,A wheel; felleeZ-l is secured on the outer rim l-,3;- byl--means of screws 22 which pass through the rin l3.' .andinto the; ring gear 20, thus rigidly 5 the, engine 24 drives the; gear 21 which is rigid,

on the shaft of the gear 12. The latter is con-- tainedin a housing 23 bolted to the ring I!) at I either end,as shown in Figure 1. The gear l2 is in mesh withthe internal gear 20 and drives the samel a I At, arcuately spaced-apart positions on the rims l;9;, pairs3 of-,ears 28, 29, 30,, 3|, 32, 33, 34, 35, and-36am mounted,,one of each pair being transversely opposite the other; Bolts 3'! join the twogearsiof each of the abovementioned pairs of, earsv and: lock the same together, these bolts thereby-securing the-rims IS in place; A link 38 is pivotally mounted on onev endto the bolt 31 of: theears 33, and atthe other end on the transversearr'n- 39 of a. square-shaped frame 40, the upperarm directly oppositexthe lower arm 39 of which-.is-pivotally mounted in similar link 4| whose; otherg end' issimilarly pivotally: mounted on theboltill of. the. ears 28,. Coiled springs 42 1 have one end secured in each ear 35and' the other endysecuredto the extensions 43v of telescopic chair armsi44awhichzalsoccntain coiled springs 45..The. otherends 46;. of the armsv 44 are pivotallyr secured to the side arms of the frame 40. A combined chair seat and back 41- has its back secured to the extensions 43 of the arms 44 and its seat joined'to the extensions 46 of these arms by .means of springs 48. It is thus apparent that the chair 4-! is, given a pivotal spring suspension within/the device to permit resilient. movement,

as shown. in broken and in full lines in Figure 1.

This construction. facilitates transferring of the weight of the driver'from a' rearward to a forward position, as may be desirable in starting or stopping the device or in facilitating its movebined foot rest and mudguard 53 is secured on the lower portion of the ring l and is slotted at 54 toward the rear so that it may curve outward and rearward of the wheel. The bolts which secure the housing 26 to the rim l0 also fasten the mudguard 53 thereto, and additional bolts, not shown, may be provided for this purpose. A pair of additional frame members 55 are mounted between the ears 3!! and the engine frame, between which a cradle 56is pivotally mounted.

Adjacent each ear 3|, a yoke bar-51 is pivotally mounted on the bolt 31, in the converging extremities of which a small auxiliary wheel 58 is rotatably mounted. Springs 59, secured to the inner extremities of the bars 51 and to the inner ring l0, normally urge the wheel 58 upward from the ground. A cable 60 is securedat one end to one yoke member 51 and at the other end to the cradle 56, by means of which the wheel 58 may be brought downward toward the ground upon rotation of the cradlef56, the intermediate length;

and path of the cable 60 being not shown. A

wheel 6|, constructed' and mounted similarly to the wheel 58,iis" provided in the same position at the rear of the device. 'Acable 62 is similarly connected to the cradle '56'through a path not shown, so that it may be similarly'operated.

Between the tire 23 and the wheel 58,- a braking device is providedon' the'yokes'51' of each wheel 58 and 6|. This device consists of a cylindrical shoe 63 rotatably mounted intermediate the length of a rod 64 which has one end pivoted in an ear 65 rigid with one yoke member 51. The rod 64 is widened at '65,'and a hole extends'therethrough for the passage therethrough of the other yoke member 51. The outer extremity 66 of the rod 64, has a cable 61 attached thereto, the other end of which is secured in the usual manner to'one of "the handle bars ortoany other convenient place where it may be readily operated by the driver. Tautening of the cable 61 will urge the shoe 63 against the tire 23 to brake the device. "The detailed constructionpf the brake, as described, is one example only, although it may be constructed in any desirable and suitable manner. Also pivotally mounted in the ears 3|, are a pair of standards 68 which normally rest in notches in the mudguard 53,

and which may be swung downward therefrom to the'position shown in broken linesin Figure 1,

so that the device may be'supported in upright position when at rest. A coiledspring 69 mounted between a cotter pin 16 and the" rod 64, normally keeps the shoe '63 away from the tire 23.

The operation of the device is obvious. The gear 21, when driven by the engine 24, rotates the internal gear 20, thus propelling the device. Balance of the device is maintained by the driver who is free to shift his weight as may be necessary. The wheels 58 and fi l'serve to prevent turning of the chassis too far from its normally upright position in case of sudden slowing down or speeding up of thedevice. Control of the position of the wheels 58 and. 6!. regulates the amount of tilting of the chassis either forward or rearward. V p

Obviously, modifications in formand structure may be made without departing from the spirit and'scope of. the invention.
